AI training may leak secrets to canny thieves

A paper released on arXiv last week by a team of researchers including Prof. Dawn Song and Ph.D. student Nicholas Carlini (B.A. CS/Math '13), reveals just how vulnerable deep learning is to information leakage. The researchers labelled the problem “unintended memorization” and explained it happens if miscreants can access to the model’s code and apply a variety of search algorithms. That's not an unrealistic scenario considering the code for many models are available online, and it means that text messages, location histories, emails or medical data can be leaked. The team doesn't “really know why neural networks memorize these secrets right now, ” Carlini says. “At least in part, it is a direct response to the fact that we train neural networks by repeatedly showing them the same training inputs over and over and asking them to remember these facts." The best way to avoid all problems is to never feed secrets as training data. But if it’s unavoidable then developers will have to apply differentially private learning mechanisms, to bolster security, Carlini concluded.

Ling-Qi Yan helps to improve computer rendering of animal fur

CS graduate student Ling-Qi Yan (advisors: Ravi Ramamoorthi/Ren Ng) and researchers at U.C. San Diego are the subject of an article in TechXplore titled "Scientists improve computer rendering of animal fur." He is part of a team that developed a method for dramatically improving the way computers simulate fur, and more specifically, the way light bounces within an animal's pelt. The researchers are using a neural network to apply the properties of a concept called subsurface scattering to quickly approximate how light bounces around fur fibers. The neural network only needs to be trained with one scene before it can apply subsurface scattering to all the different scenes with which it is presented. This results in simulations running 10 times faster than current state of the art. "We are converting the properties of subsurface scattering to fur fibers," said Yan. "There is no explicit physical or mathematical way to make this conversion. So we needed to use a neural network to connect these two different worlds." The researchers recently presented their findings at the SIGGRAPH Asia conference in Thailand.

For the second year running, UC Berkeley has won the Fiesta Bowl Overwatch Collegiate National Championship, sweeping UC Irvine 3-0. CS majors Kevin "SlurpeeThief" Royston and Gandira “Syeikh” Prahandika were on the Berkeley team, which battled in front of a sold-out crowd at the game in Tempe, Arizona, the first partnership between a collegiate bowl game and eSports tournament. Royston, who was profiled in on Overwatch Wire article before the tournament, is in the top 1% of all players worldwide, has had a peak skill rating of 4626, and was on the winning team last year. He notes that the balance between esports and school has been a tough road. “It’s definitely rough, this week is the first time I had a homework assignment slip because of Overwatch. (Laughs) Hear me out! It’s for Machine Learning which is the hardest class at Berkeley. We had to travel (for the Fiesta Bowl) and I worked sixteen hours on an assignment and didn’t even get halfway through it.” Overwatch is a team-based shooter game that was created by Blizzard Entertainment and released in 2016. Teams are made up of six players, who select different characters, known in the game as “heroes,” to complete different objectives. The Berkeley team won $42,000 of the $100,000 total in scholarships and other prizes.

Security for data analytics – gaining a grip on the two-edged sword

Prof. Dawn Song and graduate student Noah Johnson are taking a new approach to enable organizations to follow tight data security and privacy policies while enabling flexible data analysis, as well as machine learning for analysts. Working with Uber, they tested their system using a dataset of 8 million queries written by the company’s data analysts. The system is currently being integrated into Uber’s internal data analytics platform. With help from the Signatures Innovation Fellows program, they are advancing the system to provide the same level of security and flexibility for a broad range of data analysis and machine learning, whether needed in basic and medical research or business analytics.

Computer Vision to Protect Patients — and Budgets

Prof. Alexandre Bayen and PhD student Pulkit Agrawal developed a computer vision-based system to help memory care centers monitor patient falls and to reduce them where possible. State regulations require an MRI of the head any time a patient suffers an unwitnessed fall, and about a fourth of all Alzheimer’s-related hospital visits are triggered by a fall. With five million Americans currently living with Alzheimer’s, the task of preventing, tracking and treating fall-related injuries has become daunting and costly, with more than a $5 billion annual cost to medicare--and the number of people with Alzheimer’s is expected to double in the next 15 years. A system capable of detecting falls by autonomously monitoring patients and sending therapists video clips could improve the monitoring process immensely “There are no effective drugs yet to treat Alzheimer’s,” Agarwal says. “Until we have them, we have to help patients where they are. Developing computer vision systems to detect falls and fall vulnerability seemed like a good way to improve healthcare for a growing patient population.”

Berkeley's HKN Mu Chapter wins IEEE-HKN Outstanding Chapter Award

GEESE: A new cross-disciplinary student initiative to reflect on issues of society & technology

A new initiative, Graduates for Engaged and Extended Scholarship around Computing & Engineering (GEESE), aims to address growing concerns about the rapid advancement and integration of technologies in the global arena by building a coalition of engineers and social science scholars across campus to engage in issues vital to society and technology. GEESE, launched this semester as one of CITRIS's Tech for Good initiatives, plans to build a campus community of grad students and postdocs who will bring together disciplines and perspectives from fields like law, public policy, economics, anthropology, sociology, and philosophy, to promote cross-disciplinary scholarship on issues that cannot be wholly addressed from the silos of individual fields. They will hold roundtables on relevant issues to gauge students' interests, and organize seminars with thought leaders to reflect and redefine their mission and acitivities.
